Big news today is some information on casting. We have three roles:
Michelle Yeoh as Captain Georgiou. Weirdly, captain of the Shenzhou, not the Discovery. Most famous for Crouching Tiger Hidden Dragon, this is a big name for the cast, although probably a more minor role.
Doug Jones as Lieutenant Saru. Has hardly ever appeared on TV without being in some kind of monster makeup, and will be playing an alien again here.
Anthony Rapp as Lieutenant Samets. More famous as a broadway star (he was in the initial production of Rent), this will be quite a new thing for him. His character is described as a fungus expert.
Overall – interesting, but hard to see where the show is going from these.
